Instance Method Details

#clone ⇒ Object

Public: Creates a new VM which is a clone of an existing VM. As Fusion doesn’t provide a native cloning mechanism, this is a best effort. This essentially is a directory copy with updates to relevant files. It’s recommended to clone VMs which are not running.

Examples

@cloner.clone

Returns a Response with the result. If successful, the Response’s data attribute will be nil. If there is an error, an unsuccessful Response will be returned.
